Streaming Large JSON Response in Spring.
To put things simply, this method findAllStreaming() takes an OutputStream to write the whole json response into. To write json into the stream chunk by chunk we are using JsonGenerator. JsonGenerator is provided by Jackson-Core. More detailed about how to write stream event is covered in this blog post by the author of the library.

So do XML and JSON.

Ryū: fast float-to-string conversion (Java lib, 2018 paper)
Jackson already has some improvements for string-to-number conversion over stock JDK parser (https://github.com/FasterXML/jackson-core/pull/677). Would be great if they added faster number-to-string too.

Kotlin DSL is Now the Default for New Gradle Builds
Honestly, when you look at a build.gradle.kts written by someone who knows what they're doing, it's not that bad (that reminds me, I should really clean up the build.gradle.kts on my personal project, I haven't heavily edited it since I knew a lot less about gradle...). For example, here's the build.gradle.kts for Moshi, a JSON serialization library from Square. It uses the root build.gradle.kts for the project a bit, which is here. The root one is a little more complex, but that's mostly because it has to deal with a multi-release build and has to configure a few plugins, like dokka. (If you're wondering where all the library versions are, they're here, using a new feature in Gradle you might like: The version catalog)

This approach is also used by square/moshi. You can also refer this.

Apple's Swift rewrite of its Foundation framework will be open source
Best practice in Android would be Moshi, which is written by many of the same authors as Gson but is still actively maintained. It's more or less a breaking upgrade from Gson.

Converting Json to Java object
Thanks for the info. Just checked the GitHub and it is indeed the case that Gson is not maintained anymore. The main dev left Google it seems and therefore abandoned Gson. He and some other people however created a new project called Moshi that's probably intended as a kind of Gson 3.0: https://github.com/square/moshi the last commit was three months ago and there are a crowd of contributors listed so I guess that's the better option than ye olde Gson.

Help parsing JSON with Retrofit & Moshi
However i am getting an error "Expected BEGIN-ARRAY but was BEGIN-OBJECT at $". Looking over the moshi documentation (https://github.com/square/moshi) I think I need to use an adapter as my JSON response starts with "{ }" not the expected "[ ]". I am just struggling to understand how to implement the adapter as I think the built in adapter should work.
- Moshi 1.13.0 with Kotlin 1.6 compatibility now available
